SELF-SETTING HAIR-TRIGGERED GUN-LOCK.

Specification of Letters Patent No. 16,634, dated February 17, 1857,

To all whom it may concern.

Be it known that- I, Joni-trims ALTMAN, of the county of Armstrong and State of Pennsylvania, have invented a new (inn- Lock, and that the following is a full, clear, and exact description of the principle or character which distinguishes it from all other thii'igs before known and of the usual manner of making, modifying, and using the same, reference being had to the annexed drawings.

Figure 1 shows the lock and. all its parts in the position when the gun is eocked" ready for firing. Fig. 2, shows the trigger plate and the parts connected with it, detached and exhibits these parts in their respective positions, when the hammer is down; Fig. 3, a top view of the lock.

The object of the above stated improvements is to produce a gun lock which will set the triggers of a double or hair trig gered gun by the mere act of drawing back the hammer or as it is commonly called cocking the gun. It may therefore be described as a self setting hair-triggered gun lock.

The improvement is intended to apply to those locks in common use for double triggered rifles. In those locks now in use there is a lever constituting the upper part of the tumbler which is moved by the motion of the hammer as on a pivot. This lever or shaft in my improved lock is lengthened and extended (as shown at A,) in toward the breech of the gun so that the end may work clear of the tumbler. To

that end of the said lever next the breech is pivoted another lever B of a shape slightly curving downward toward the trigger, the free end of which acts upon one arm of a double lever C now to be described. This double V shaped lever is pivoted to a standard D on the trigger plate just in front of the hair trigger. One prong of this V lever curves downward to the hind trigger 1*] so as to act on said trigger when the hammer of the lock is drawn ba k ard. The other prong of said double lever curves upward and is acted upon by the before mentioned lever 13 that is fastened to the end of the shaft or lever at the upper part of the tumbler.

When the hammer is drawn backward and the gun is cooked at a single draw, the lever B is projected forward against the end of the one prong of the double lever, and moving it downward moves at the same time the other prong against the main trigger E of. the gun the end of which is forced under the catch in the head of the hair trigger I and thus the triggers are set. The triggers may be set also by drawing back the hind trigger in the ordinary way.

hat I claim as my invention is The mode herein described of setting the double trigger lock by the act of cooking the gun as set forth,

JONATHAN ALTMAN.
